To all av/1.0m it may concern:

Be it known that I, FREDERICK Comm, a citizen of the United States,residing at \Vyoming, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in Machines for SecuringEnd Closures in Vessels, of wlnch the following is a specification.

This invention relates to the manufacture of cartons such are made ofpaper and the like and which have a body portion provided with top andbottom heads, one or both heads being fixed to the body by glue orpaste.

More particularly the invention relates to a machine for securing endclosures in ves-. sels of the character named.

It is well recognized that strength is glven the ends of cartons of thisclass if the closures or heads are so formed as toproject into the body,or technically speaklng, are bumped inwardly. In such cases where theclosures are secured by glue or paste a head may consist of a flat disklike central portion surrounded by a rim whiclrbeags against the insideof the bod and 1s crimped over to engage the outside of the body.

One important object of the present 1nvention is to provide a simplemachine of improved construction for applying such heads to cartonbodies.

In preparing heads of the above described character the crimping over ofthe rim is partially effected in the manufacture of the head but thecrimped over portion of the rim is left flaring outwardly so that thehead may more readily be applied to the bod A second important object ofthe invention is to provide a machine having simple and improved meansf01 fo1c1ng thls flaring portion inward against the carton body.

ressure applied to the outside of such heads around their peripherytends to distort the head unless means are provided to maintain itsform. I

A third object of the present invention is to provide a novelarrangement and operation of supporting die for the bumped portions ofsuch heads whereby distortion or collapse of the head will be prevented.

With the above and other objects in view, as will be hereinafterapparent, the invention consists in general of certain novel details ofconstruction and combinations and arrangements of parts hereinafterfully described, illustrated in the accompanying drawings andspecifically claimed.

In the accompanying drawings like characters of reference indicate likeparts in the several views, and

Figure l is a side elevation partly in section of a machine constructedin accordance with this invention, the parts being shown in thepositions assumed before operating on a carton.

1g. 2 is a partial side elevation. also partly in section, with theparts in the positrons assumed when the operating on a carton iscomplete.

Fig. 3 is a vertical section through the upper part of a certain plungerused in connection with other devices to form the invention, the sectionbeing taken on the line 33 of Fig. 1.

Fig. 4 is a section on the line 44 of Fig. 2.

Fig. 5 is a View similar to Fig. 4 but disclosing a modification of theportion of the machine there shown.

Fig. 6 is a section on the line (j o of Fig. 5.

It is to be understood that thc embodiment of the invention illustratedin the drawlngs and now to be described is merely' one of many ways inwhich the invention may assume concrete form. This embodiment istherefore to be taken as simply typical of a variety of forms which theinvention may take.

In this embodiment there is provided a standard 10 which may be securedto any suitable foundation such as a floor or table. This standardcarries a table 11 and on the standard above the table is a slidablesleeve 12 held in adjusted position on the standard by means of a setscrew 13. Projecting from the sleeve 12 is an arm 14 carrying at itsouter end a sleeve 15 wherethrough extends.

reciprocably the stem 16 of a plunger having a head 17. This stem ishollow for purposes hereinafter to be described, being provided with anaxial opening 18 having an enlarged upper end 19 normally closed by acap 20. esting on the cap 20 is a roller 21 which is revolubly mountedon a lever 22. This lever has one end pivoted as at 23 to a collar 24mounted on the upper part of the standard 10 and held in adjustedposition by a set screw 25. Thus the construction is such that bypressing the free end of the lever downwardly the plunger is depressed.In order normally to hold the plunger raised tension springs 26 ha ve.their lower ends connected to the head as at 27 and their upper endsconnected to plus or screws 28 projecting from the sleeve 15. Thus afterthe plunger is depressed and the lever released the springs will raisethe plunger and restore it to its original position.

Depending from the head 17 are spaced pairs of lugs 29 and between thelugs of each pair lies a lug 30 which projects outwardly from a cartonperiphery engaging member 31, these members being so arrange as to lienormally in downwardly and inwardly inclined positions and to completelysurround a carton head. These members further have their lugs 30connected to the respective lugs 29 by pins 32,the connection being thusa pivot or lnnge connection. Normally these members are kept in inclinedposition by springs 33 seated in recesses 34 in the head 17 and inrecesses 35 in the members 31.

It will be noted that no restriction exists as to size or shape of theplunger head an two different shapes of the many which may be used arehere shown, a head for circular cartons being shown in Figs. 1, 2 and 4an a head for square cartons being shown in Figs. 5 and 6. It will beobvious that other forms such as hexagonal, diamond shaped, oval and thelike can readily be'made. It will be noted however that whereas recesses36 are formed in circular heads for convenient assembly of the pins 32,heads such as shown in Fig. 5 will require the corner lugs 29 to beshorter than the intermediate lugs.

On the under side of the table is a sleeve 37 in axial alinement withthe plunger, the opening in the sleeve being continued through the tableso as to accommodate a stem 38 which is held in adjusted position in thesleeve by a set screw 39. On the upper end of the sleeve is a cartoncarrier or holder 40 whereon may rest a carton A having a bumped head Band crim ed over rim C. Surrounding the carton ho der is a split hollowcylinder or prism consisting of two halves 41 connected by hinges 42 andbeing of such height that depression of the plunger will bring themembers 31 into contact with the top of the cylinder and thus force theinner portions of these members upwardly with reference to the plun erwhereby they engage with and contract t e rim C of the carton.

In order to support the inside of the bumped head B a die 43 is providedwhich fits the inside of said head closely and is carried on a stem 44slidable in the opening 18 of the plunger. The upper end of this stem dholder carries a collar 45 which is held in position by a pin 46, thepurpose of this construction being to permit change of dies to which endthe cap 20 may be removed and the stem 44 raised until the pin 46 can bewithdrawn whereupon the collar will be released and the die dropped downtill the stem 44 is free from the head 17. The reason for mounting thedie slidably with relation to the head will be apparent when it itconsidered that a rigid mounting of the die would either limit themovement of the plunger or result in destruction of the carton head B.

In order to cause proper cotiperation bed tween the die and the members31 the latter are provided each with a groove 47 and the die is providedwith a flange 48 engaged in the grooves so that movement of the members31 is accomplished by corresponding movement of the die whereby thelatter constitutes in effect an anvil supporting the work (the rim 0) tobe acted on by the members 31.

In operation paste is applied to one end of a carton body as by thedevice shown in my copending application filed September (1 25, 1920,and bearing the Serial Number 412,833. The head is then positioned onthe body and the prepared carton placed in the 40, the split cylinderhaving been opened for that purpose. The split cylinder is then closedand the lever depressed. This causes the parts to assume the positionsshown in Fig. 2 and the rim C is thus crimped firmly against the cartonbody. The lever is then released and the finished carton removed.

There has thus been provided a simple and efiicient device of the kinddescribed and for the purpose specified.
